The universe as a quantum gravity condensate
Daniele Oriti
This is an introduction to the approach to the extraction of cosmological dynamics from full quantum gravity based on group field theory condensates. We outline its general perspec…
Holographic two-point functions for Janus interfaces in the CFT
Marco Chiodaroli, John Estes, Yegor Korovin
This paper investigates scalar perturbations in the top-down supersymmetric Janus solutions dual to conformal interfaces in the CFT, finding analytic closed-form solutions.…
Efficient entanglement distillation without quantum memory
Daniela Abdelkhalek, Mareike Syllwasschy, Nicolas J. Cerf +2
Entanglement distribution between distant parties is an essential component to most quantum communication protocols. Unfortunately, decoherence effects such as phase noise in optic…
Early Universes with Effective Discrete Time
Laurent Baulieu
The mechanism for triggering the universe inflation could be that at very early periods the time variable was discrete instead of smooth. Alternatively, and perhaps equivalently, i…
Validating gravitational-wave detections: The Advanced LIGO hardware injection system
C. Biwer, D. Barker, J. C. Batch +44
Hardware injections are simulated gravitational-wave signals added to the Laser Interferometer Gravitational-wave Observatory (LIGO). The detectors' test masses are physically disp…
Comments on: "Echoes from the abyss: Evidence for Planck-scale structure at black hole horizons"
Gregory Ashton, Ofek Birnholtz, Miriam Cabero +7
Recently, Abedi, Dykaar and Afshordi claimed evidence for a repeating damped echo signal following the binary black hole merger gravitational-wave events recorded in the first obse…
Logarithmic corrections to black hole entropy from Kerr/CFT
Abhishek Pathak, Achilleas P. Porfyriadis, Andrew Strominger +1
It has been shown by A. Sen that logarithmic corrections to the black hole area-entropy law are entirely determined macroscopically from the massless particle spectrum. They theref…
Modeling dynamical ejecta from binary neutron star mergers and implications for electromagnetic counterparts
Tim Dietrich, Maximiliano Ujevic
In addition to the emission of gravitational waves (GWs) the coalescence and merger of two neutron stars will produce a variety of electromagnetic (EM) signals. In this work we com…
Finite temperature quantum field theory in the heat kernel method
Yuri V. Gusev
The trace of the heat kernel in a (D+1)-dimensional Euclidean spacetime (integer D > 1) is used to derive the free energy in finite temperature field theory. The spacetime presents…
Conformal anomalies and the Einstein Field Equations
Hadi Godazgar, Krzysztof A. Meissner, Hermann Nicolai
We compute corrections to the Einstein field equations which are induced by the anomalous effective actions associated to the type A conformal anomaly, both for the (non-local) Rie…
On the integral law of thermal radiation
Yuri V. Gusev
The integral law of thermal radiation by finite size emitters is studied. Two geometrical characteristics of a radiating body or a cavity, its volume and its boundary area, define…
The most powerful astrophysical events: Gravitational-wave peak luminosity of binary black holes as predicted by numerical relativity
David Keitel, Xisco Jiménez Forteza, Sascha Husa +9
For a brief moment, a binary black hole (BBH) merger can be the most powerful astrophysical event in the visible universe. Here we present a model fit for this gravitational-wave p…
Semi-abelian Z-theory: NLSM+phi^3 from the open string
John Joseph M. Carrasco, Carlos R. Mafra, Oliver Schlotterer
We continue our investigation of Z-theory, the second double-copy component of open-string tree-level interactions besides super-Yang-Mills (sYM). We show that the amplitudes of th…
A stochastic template bank for gravitational wave searches for precessing neutron-star--black-hole coalescence events
Nathaniel Indik, K Haris, Tito Dal Canton +5
Gravitational wave searches to date have largely focused on non-precessing systems. Including precession effects greatly increases the number of templates to be searched over. This…
Testing loop quantum cosmology
Edward Wilson-Ewing
Loop quantum cosmology predicts that quantum gravity effects resolve the big-bang singularity and replace it by a cosmic bounce. Furthermore, loop quantum cosmology can also modify…
Structure of Stable Binary Neutron Star Merger Remnants: Role of Initial Spin
Wolfgang Kastaun, Riccardo Ciolfi, Andrea Endrizzi +1
We present general relativistic numerical simulations of binary neutron star (BNS) mergers with different initial spin configurations. We focus on models with stars of mass 1.4 M_s…
Upper Limits on the Stochastic Gravitational-Wave Background from Advanced LIGO's First Observing Run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +992
A wide variety of astrophysical and cosmological sources are expected to contribute to a stochastic gravitational-wave background. Following the observations of GW150914 and GW1512…
New Relations for Gauge-Theory and Gravity Amplitudes at Loop Level
Song He, Oliver Schlotterer
In this letter, we extend the tree-level Kawai--Lewellen--Tye (KLT) and Bern--Carrasco--Johansson (BCJ) amplitude relations to loop integrands of gauge theory and gravity. By rearr…
First Demonstration of Electrostatic Damping of Parametric Instability at Advanced LIGO
Carl Blair, Slawek Gras, Richard Abbott +16
Interferometric gravitational wave detectors operate with high optical power in their arms in order to achieve high shot-noise limited strain sensitivity. A significant limitation…
Gravitational waves and mass ejecta from binary neutron star mergers: Effect of the stars' rotation
Tim Dietrich, Sebastiano Bernuzzi, Maximiliano Ujevic +1
We present new (3+1) dimensional numerical relativity simulations of the binary neutron star (BNS) mergers that take into account the NS spins. We consider different spin configura…
Complex structure-induced deformations of sigma-models
Dmitri Bykov
We describe a deformation of the principal chiral model (with an even-dimensional target space G) by a B-field proportional to the Kähler form on the target space. The equations of…
All-sky search for short gravitational-wave bursts in the first Advanced LIGO run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +986
We present the results from an all-sky search for short-duration gravitational waves in the data of the first run of the Advanced LIGO detectors between September 2015 and January…
The Braking Index of a Radio-quiet Gamma-ray Pulsar
C. J. Clark, H. J. Pletsch, J. Wu +14
We report the discovery and timing measurements of PSR J1208-6238, a young and highly magnetized gamma-ray pulsar, with a spin period of 440 ms. The pulsar was discovered in gamma-…

Xiang Li, Yi-Ming Hu, Zhi-Ping Jin +2
Neutron starblack hole (NSBH) coalescences are widely believed to be promising gravitational wave sources in the era of advanced detectors of LIGO/Virgo but such binaries hav…
